Reynaud, Grosse Pointe Park, Mich.Application February 13, 1956, Serial No. 565,133 10 Claims. (Cl. 20-42)This invention relates to improved awning type window structures andmore particularly, but not exclusively, to an operating and lockingmechanism for such window structures.

One important object of the invention is to provide a window structurehaving vertically swingable sashes arranged to swing about horizontallydisposed hinge pins so as to permit the sashes to be moved to variouspositions of adjustment and to provide improved operating and lockingmeans therefor so constructed as to facilitate the operation of suchsashes and the locking thereof in their closed position.

This and other objects are accomplished by the practice of the instantinvention, one feature of which includes a window structure comprising aframe having side and end members and a sash swingably mounted upon theframe and adapted to hold a sheet of glazing material. A slidableactuating bar is positioned in a recess within the frame and supportsthe sash upon a pivot. The sash is also swingably secured to the frameby a link pivoted at one end upon the sash and pivoted at the oppositeend upon the frame. The link includes ahook portion at the end thereofpivoted upon the sash. The actuating bar carries a pin rigidly mountedthereon and projecting therefrom and positioned selectively to.

engage and to disengage the hook portion of the link when thesash isswung into its closed position Within the frame and the bar is moved ina predetermined direction.

The invention will be described in greater detail in connection with theaccompanying drawings of which:

Fig. 13 is a sectional view of the structure shown in Fig. 1 taken alonga section line (not shown) closely adjacent to and looking in theopposite direction from the section line 22. This figure shows thestructure in a different operative position from that illustrated inFig. 1.

In the drawings, wherein for the purpose of illustrating the inventionthere is shown a preferred embodiment thereof including the operatingmechanism for the sash members and the various parts incident thereto,the reference character 20 will be generally employed to designate awindow frame formed of channel bars or the like including side, top andend bars arranged with their ends connected together in rectangularrelationship. The side bars 23 and 25 are of generally channel shape asthe side bar 23 shown in detail in the drawings. The side bar 23, andalso the bar 25, includes an outer wall 22 shaped to form a separatelocking channel 24 having enclosing flanges 26 and facing inwardlytoward the main channel of the side bar. The side bars 23 and 25 areadapted to be rigidly secured as by screws or bolts passing therethroughto a structural member of a wall opening in a building or the likethereby securing the frame rigily in place.

The window frame 20 is provided with a series of vertically slidable andswingable sashes 30 and 32 which are rectangular in construction and maybe formed of either Wood or metal moldings as desired. The instantdescription will be concerned with wooden sashes although it is to beunderstood that metal sashes may be substituted therefore according toknown techniques. Glass window panels 34 are installed in the sashes andmay be held in place conventionally as by molding strips, glazingtriangles and putty (not shown). Each of the sashes includes two framemembers 36 and 3S fastened together in overlapping relationship toprovide a sealing face 44) extending along the sides of the sash. Whenthe sash is in its closed position, the face 40 abuts against aresilient gasket 42 held in the outer wall 22 of theside bar by means ofa channel groove 44 as shown in Fig. 4. The inner frame member 38 of thesash closes against a gasket 48 similarly held in a channel 50 in theinner wall 46 of the side bar.

A slide bar 52 (Figs. 1 and 6-9) is slidably mounted within the channelof the side bar 23, shown in Fig. l at the right-hand side of thewindow, although if desired it, together with its enacting elements,maybe transposed to the left-hand side of the window to operate in anstructure comprising only two sashes in vertical array,

the invention is equally applicable to window structures including anarray of one, three or more sashes. If the structure includes only onesash, it will be operated in the manner hereinafter to be described withrespect to the lower sash 32. If the window includes more than twosashes in vertical array, all the sashes except the bottom one would beconnected and operated in an identical manner to the upper sash 30.

The sashes are pivotally mounted on the slide bar by means of brackets68 and 69. Each of the brackets includes a dog-leg portion 72 extendingupwardly and inwardly toward the interior of the window structure. Thebrackets may be secured to the sashes by any convenient means such asthe screws 70. Pivotpins 74 and 75 extend through holes in the dog-legportions of the brackets to fasten the brackets to the slide bar. Thesepins pass through the brackets and the slide bar 52 into the lockingchannel 24 in the wall 22 (Fig. 6) where they are retained and locked bymeans of slidable locking plates 80. These pins 74 and 75 are theprincipal retaining means to hold the slide bar 52 in its operativeposition within the channel of the side bar 23 of the window frame. Thelower and upper sashes are, additionally, linked to the side bar 23 bythe links 84 and 86, respectively. The link 86 attached to the uppersash includes a locking hook portion 87 and is pivoted at one end uponthe upper sash 30 by one of the screws 70. At its opposite end it ispivoted upon a screw 88 at a fixed point along the side bar 23. The link84, associated with the lower, or bottom sash 32, is pivoted at one endupon a bracket screw 70 attached to the sash frame. The other end ofthis link 84 is pivoted upon a screw or pin 90 at a fixed point alongthe side bar 23.

It will thus be seen that the sashes are mounted so as to be responsiveto a sliding motion imparted to the slide bar 52. i. e., movement of theslide bar causes the sashes to swing about axes defined by the screws 70that secure the ends of the respective links 84 and 86, Whilesimultaneously the axes of the sashes swing about the pivot pins 88 and90 by which the links are secured to the side bar.

The slide bar 52 is actuated by a crank and worm mechanism generallydesignated 54 to which it is connected by a draw bar 51. The crank andworm assembly forms no part of the instant invention and may be ofconventional construction. It may include, for example, an operatorcrank 92 which turns a worm (not shown) to drive a worm wheel (notshown) to turn the actuating crank 56. The actuating crank 56 ispivotally connected by a screw 58 or any other suitable means such as arivet to one end of the draw bar 51. The slide bar 52 is connected tothe other end of the draw bar 51 by means of the pin 75 heretoforedescribed that also retains the lower sash bracket 69 and the slide bar52 in position.

The bracket 68 that holds the upper sash 30 is fitted with an auxiliarypin 94 closely adjacent to the pivot pin 74 in the dog-leg portion ofthe bracket. This pin, as shown in greater detail in Fig. 8, projectsfrom the bracket into a shaped, lost motion and cam aperture 96 in theslide bar. This aperture serves two purposes. First, it permits apredetermined movement of the slide bar independently of the movement ofthe sash so that, as hereinafter described, the slide bar may be moveddownwardly to unlock the sash before it exerts a downward force upon thepivot pin 74 of the sash. Secondly, it is shaped to limit the movementof the pin combination (the pivot pin 74 and the auxiliary pin 94) tohold the window rigidly in a fixed position at any point in the travelof the slide bar.

The link 86 by which the upper sash 30 is connected to the side bar 23of the window frame includes a hook portion 87 at the end of the linkthat is pivoted upon the sash. This hook is shaped to cooperate with apin 98 mounted upon the slide bar and shown in greater detail in Fig. 9.The pin 98 is secured within the side bar retaining channel 24 of thewindow frame by means of a slidable plate 100 and it, also serves toretain the slide bar 52 in its desired position within the side barchannel.

A locking device, generally designated 102 and shown in detail in Figs.through 12, is disposed in the opposite side bar 25 of the window framefrom the slide bar. This lock includes an auxiliary link 104 slidablymounted within the channel of the left-hand side bar 25 of the windowframe. The link 104 is pivoted upon a lever 106 by a rivet or pin 108.The lever 106 has a handle portion 110 which projects through a slot inthe Wall of the side bar 25 into the interior of the building in whichthe window is mounted. The lever is pivoted to the frame and held inalignment as by the screw 112 so that a swinging d movement of thehandle 110 produces generally rectilinear movement of the link 104. Asash supporting link is connected between the lower sash 32 and the sideframe bar 25. This link 105 is generally similar to the link 86connected to the opposite side of the upper sash 30 and has a cam-shapedhook portion 107 at its upper end adjacent to its pivot point 109 uponthe sash. A pin 114 projects from the side of the link 104 at the upperend thereof and in a position to be engaged by the hook 107 when thesash is closed and the lever handle 110 is raised. The hook 107 and pin114 thus lock the lower sash firmly and rigidly in a closed position.The hook is preferably formed as a cam with sloping sides so that as itengages the pin it tends to draw the sash inwardly toward the frame toinsure a weather-tight seal between the sash and the gaskets 42 and 48.The sides of the sashes opposite from the crank and worm mechanism 54-and adjacent to the left side bar 25 may be supported by a slide bar andlink assembly generally similar to the assembly heretofore describedexcept that an actuating crank and draw bar need not be included. Thesashes generally are sufficiently rigid to maintain themselves inalignment.

In operation with the relative parts positioned as shown in Figs. l-l2,the window sashes 30 and 32 are in a fully closed position and arelocked against unauthorized opening from the outside of the building bymeans of the interengaging hooks and pins, the hook 87 being associatedwith the upper sash and engaging the pin 98 as shown in Fig. 2, and thehook 104 being associated with the lower sash and engaging the pin 114as shown in Fig. 12. In this position the slide bar 52 is in its fullyraised position and the window sashes are completely closed relative tothe frame 20.

Should it be desired to open the window sashes 30 and 32, the slide bar52 may be moved downward in a vertical direction by turning the operatorcrank 92 which is connected through the worm and wheel assembly 54, theactuating crank 56 and the draw bar 51 to the slide bar. Before theoperator crank is turned, however, the locking lever 106 must bedepressed to release the pin 114 on the lower sash from engagement withthe hook 104 in order to free the lower sash 32. As the slide bardescends the lower sash 32 starts to open and, simultaneously, the pin98 is withdrawn from engagement with the hook 87 of the upper sash link86. As the pin is drawn free of the restraining edge of the hook, theedge of the slide bar defining the aperture 96 is brought into contactwith the pivot pin 74 that holds the upper sash bracket 68. Furtherdownward movement of the slide bar 52 moves the pivot pins 74 and 75 ofthe two sashes downwardly and in cooperation with the links 84 and 86forces the sashes to swing outwardly. When the slide bar reaches itsfully extended downward position, the relative parts are in the positionshown in Fig. 13 and the sashes are substantially fully open in analmost horizontal position.

The links 84 and 86, it should be noted, are pivoted upon the respectivesashes at points closer to the bracket pivots 74 and 75 than to thelower edges of the sashes. Thus, the sashes are unbalanced so that theirweight tends to close them and the force exerted by the sashes upon thepivot pins 74 and 75 is in an upward direction when the sashes are in anopen position.

When it is desired to close the sashes 30 and 32, the slide bar 52 ismoved upwardly by turning the operator crank in its reverse direction toswing the actuating crank toward its vertical position. The weight ofthe sashes themselves assists in this operation so that relativelylittle force is required of the actuating crank. The upper sash 30closes first as the slide bar is raised after which the lower sashcloses and the hook 87 is engaged by the pin 98 to lock the upper sashin its closed position.

It will thus be seen that the improved mechanism herein describedprovides a window structure wherein all of the operative parts areconcealed and which is relatively simple and rugged in constructiontion.
